At 10:30 p.m., surgeons at Interim LSU Hospital were attempting to remove the fragments, McGregor said.

David Sean Jackson Sr., 26, of New Orleans, was arrested in connection with the shooting, McGregor said.

The confrontation began about 2 p.m. when two vehicles -- a red 2007 Chevrolet and a 2004 green Acura -- were traveling westbound on I-10 near the split with Interstate 610, police said. The boy rode in the backseat of the Chevrolet while his mother's 50-year-old boyfriend drove, police said.

Jackson was driving the Acura with his two sons -- a five-month-old and a 6-year-old -- and their 25-year-old mother, in the car, police said.

The driver of the Chevrolet cut Jackson off by passing him, then switching back to Jackson's lane, starting the tiff, police said. The two cars continued cutting each other off.

As they passed the Clearview Parkway exit, Jackson fired a gun "three or four times" from the middle lane into the Chevrolet, which was traveling in the far left lane, McGregor said.

The driver of the Chevrolet then "rammed" the Acura and pursued Jackson down the Williams Boulevard exit in Kenner, eventually hitting the the Acura a second time at the corner of Williams and Driftwood boulevards, McGregor said.

Police arrested Jackson, who was on parole in New Orleans for distribution of drugs and felony possession of a firearm.

Jackson was charged with aggravated criminal damage to property, attempted second degree murder, illegal possession of a firearm by a felon, illegal carrying of weapons and possession with the intent to distribute crack cocaine and other traffic violations.

Kenner police have asked anyone with information to call Detective Shaun Watson at (504) 712-2240 or Crimestoppers at (504) 822-1111.
